This is great information. I've been avoiding the parking brake after reading about the issues here. I guess I'll have to start giving it a tug...once the car has been turned off, of course.

I bought one of the first 2007 E70s, hence no AUTO H. If this problem with the parking brake ever gets fixed....can I use it in lieu of AUTO H?

I just received the latest software update (E070-08-05-520) that finally fixed the parking brake bug. My SAV was in the dealership 3 times since March because of fault code 6032 due to jammed parking brake. I hope that this one is the real fix.

Cool.

I'll be adventurous and try using the park brake before turning off the engine (when I'm driving by myself) to see if the problem really has been fixed.

Since the workaround is so effortless, I'll use that method when applying the brake when there are passengers in the car.

Just curious. Is there any truth to this statement:
"It is important to apply your parking brake when you park. It will protect your gears from stripping".

A Caddy mechanic told me that this was true when on any sort of incline. He said, if you noticed that when you set a car in park, then let off the brakes that you'll notice the car roll slightly. It puts the gears in a wrong position and when re-engaging the gears cause slight unnecessary rubbing. Over a long period of time this may lead to a slight stripping of the gear. He claims the parking brake will prevent this shift.

His explanation does make some sense. What are your takes?

rh71. I just took delivery of the car over the weekend

I didn't want to say anything on the board until I get some pictures of it. Hopefully I'll have some time this weekend. The car is awesome. Just not fond of the gas consumption though.

Nonsense. Stripped gears means that the gear teeth are knocked off, and the gears no longer engage.

When you put a vehicle in park, it has little to do with the gears. There is a pawl, which is a little arm, that engages and stops the output shaft turning. It is built fairly light, and if you ever put a vehicle in park while it is rolling, you risk breaking the pawl. The gears, meanwhile, are all at rest. Without the clutch packs engaged, they are simply idling, same as neutral.

Using a parking brake is logical, as it is safer. On a steep hill, it also prevents too much load being applied to the parking pawl.

^ well that pawl audibly creaks a lot at stop (engaging parking brake and releasing foot brake) and start (releasing brake and backing out)... on a very slightly inclined driveway. I guess it's as normal as possible...
